Robles (back spasms) will likely get two rehab appearances before rejoining the team, Christopher Smith of MassLive.com reports.
Robles, who has been one of the more reliable arms in a shaky bullpen, was placed on the 15-day injured list, retroactive to May 25. Smith adds Robles is expected to return to the Red Sox during their series versus the Angels -- he's eligible to be activated from the IL on Thursday, assuming he doesn't suffer a setback.
